Allergies

Allergy Causes and Remedies

An allergic reaction occurs when the immune system overreacts to a foreign protein in the air, in food or on the skin, releasing chemicals called histamines that make you cough, sneeze, get stuffed up, and have itchy eyes or even a skin rash. Luckily, prevention and treatment can make allergies and asthma more of a nuisance than a threat.
